Avride C++ Software Engineer interview questions

The process was very weird, I had an HR call in which I was said to have moved to the next round for a technical screen. Than the HR ghosted me for more then 2 weeks after taking my availability. When I followed up she sent a greenhouse availability link. I opened the link and some slots were there and then a few hours later it expired. I contacted HR about this thrice in two days and they sent a rejection email from a automatic mailbox.
